Many people will use two phone cards for work or life reasons, one for office and one for family; However, as a popular Apple phone, it has not been able to support the function of dual card and dual standby, which causes many iPhone users to install two phones on their bodies, which is very inconvenient.

Next, Rainy Night will introduce this K2 mobile phone case that can allow one Apple phone to have dual cards and dual standby at the same time

This back clip Apple dual card dual standby protective case IKOS-K2 is developed and produced by Shenzhen Mingda Tongda Technology Co., Ltd. It is a company dedicated to the R&D, production and sales of Bluetooth creative products. In the first half of this year, the company launched a K1S, which belongs to the form of a key bag. It can be hung on the key chain or the zipper buckle of a handbag, which is also very good; This K2 is designed as an Apple 6/6S protective case, which can be directly used as a mobile phone case, killing two birds with one stone.

Unpacking

K2 apple shell is packed in a white paper box, with the word "IKOS" printed on the front and some brief introduction and instructions related to use printed on the back

Side LOGO

▼ On the day of receiving the goods on a rainy night, it was still raining slightly outside. After opening the package, this K2 looked similar to an ordinary iPhone protective case. It was painted with black metal from Xuanyan, with a very fine matte texture, wear-resistant and scratch resistant.

▼ On the other hand, there is a SIM card slot in the middle of K2, which is used to install mobile phone cards: the smallest Nano SIM card and Micro SIM card are supported

Factory accessories also include a SIM card holder and a one to two charging cable (supporting the dedicated socket for Lightning of Apple phone and microUSB of K2 respectively)

Very simple instructions

Usage

First of all, I would like to tell you that the iPhone 7 is currently used on Rainy Night, because the size of the camera is slightly different from that of 6/6S, and it has increased a little, so that the camera will be somewhat blocked after it is installed directly. Rainy Night personally measured that the installation on my friend's iPhone 6S fits very well, and the size is just right! I wanted to give it to a friend, but later I thought that the size of the iPhone 7 was basically the same as that of the 6S, except that the camera was a little larger. Let me consider whether I can make small changes to make it match my small 7?

If it is directly put on, the camera hole of K2 mobile phone case will block the camera and flash of the phone, which will affect normal use!

What should I do? First, we should study the internal structure of this K2. If we plan to expand the hole position in the camera area, will it interfere with the internal structure of K2? There is a plastic cover plate on the inside. Try to pry it open with a blade gently on rainy nights. There is a 500mAh lithium battery, a circuit board, SIM card slots (2), Bluetooth modules, charging ports and other internal accessories. After careful comparison of the camera position, it is just on the side of the upper speaker. If the pre opened hole is properly enlarged, it should not touch the speaker and wires.

Draw a mark first, and prepare to find the drilling machine for reaming

Because it is a hard shell made of plastic, it is still very good to drill a hole on the drilling machine. After drilling the hole, use sandpaper to slightly rest it, and the appearance looks basically unchanged.

In this way, a K2 dual card dual standby protective case suitable for iPhone 7 is ready.

Next, we will install the software

First search and download the "IKOS" app in the Apple App Store

Next, you need to turn on the Bluetooth function of the iPhone, and you need to turn on K2. Press the small round button on the back of the K2 phone case with your hand for 5 seconds. When you see the red indicator light flashing at the bottom of K2, K2 will start up.

Open the IKOS exclusive to K2, find the setting --- scanning device, and verify its password (the initial password is 4 zeros) when binding K2 for the first time. After verification, you will be prompted that it has been bound.

There are some small functions in APP, which are very practical: for example, quick SMS reply (automatic setting is supported); For example, position scanning and positioning, finding K2 and making a long sound, etc

The main card of Rainy Night is the mobile card. This time, the secondary card (Xiaomi phone card) Unicom signal is installed on K2, and it can be used normally. The outgoing speed of the K2 secondary card is basically the same as that of the main card, and the incoming call is also the same. See the video below:

Summary and suggestions

Advantages: This Apple K2 dual card protective case uses Bluetooth to connect mobile phones. It has good stability. In recent days, there has been no disconnection; When used as a secondary card, the secondary card will not incur mobile network traffic charges; The modified K2 can not only fit the iPhone 6/6S, but also the iPhone 7; Built in 500mAh battery, normal use for more than two days.

Personal suggestions: 1. Can you add a small connection accessory? When the iPhone is powered off, you can use the power of this K2 to keep the iPhone in use for an additional period of time (power bank function); 2. Personally, I don't think it is necessary to configure the K2 speaker. I can use the iPhone speaker directly
